TEETH AND GUMS
Sodium tripolyphosphate (STPP), antioxidants, zinc
Peridontal disease is the most common infection in dogs and cats that leads to gum inflamation, plaque and tartar.
Tartar (or calculus) is deposits of calcium on teeth. STPP absorbs calcium resulting in reduction of calcium available for formation of tartar.
Anti-oxidants help with reducing inflammation of gums. Two of the best vitamins are E and C.
Zinc is important for strengthening gums and inhibit plaque formation.
Crunchy kibbles scrape teeth that act similar to brushing.
